Peacock bass are not considered saltwater fish because they primarily inhabit freshwater environments. These fish thrive in rivers, lakes, and streams, particularly in the Amazon basin and other tropical regions.
According to the American Fisheries Society, the classification of fish into freshwater or saltwater species is based on their habitat preferences and physiological adaptations. Freshwater fish, like the peacock bass (Cichla spp.), are adapted to live in low-salinity environments.
The underlying reason for this classification is the physiological differences between freshwater and saltwater fish. Freshwater fish, such as the peacock bass, possess kidneys that efficiently process low-salt concentrations. They also have gills that allow them to excrete excess water, maintaining osmoregulation—the balance of salts and water in their bodies. In contrast, saltwater fish are adapted to conserve water and excrete excess salts due to the higher salinity in their environments.
Osmoregulation is the process that helps fish control the balance of water and salt in their bodies. Freshwater fish absorb water through their skin and gills, while they need to excrete diluted urine to prevent overhydration. Conversely, saltwater fish must drink seawater and excrete concentrated urine to prevent dehydration.
Specific conditions contribute to the peacock bass’s classification as a freshwater species. The peacock bass typically prefers warm water bodies with abundant vegetation, such as the slow-moving waters of rivers and floodplain lakes. They rely on these habitats for spawning and feeding. Efforts to introduce peacock bass into brackish or saltwater environments generally lead to poor survival rates, as their biological adaptations are not suited for such conditions.
